Aspose.Tasks Product Family

Hi,


I’d like to generate the MPP file as attachment by Aspose , but I found that the file I generated always have some problems, can you provide example code for me to generate the file correctly?

In addition, we focus on these columns: Start, Finish, Duration, Work, Actual Start, Actual Finish, Actual Duration,Actual Work, %Work Complete, %Complete, Predecessors, Resource Names.

Hi Zhencheng,

Thank you for contacting Aspose support team.

Following is the sample code with demonstrates all the required features mentioned above. Please give it a try and share the feedback with us.

} 
catch(ParseException e) { e.printStackTrace(); }

System.out.print(“Execution completed successfully”);
}
// write your code here
